15786-53-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15786-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,8 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15786-53:
(7*1)+(6*5)+(5*7)+(4*8)+(3*6)+(2*5)+(1*3)=135
135 % 10 = 5
So 15786-53-5 is a valid CAS Registry Number.

C-acylation of enolates from lithium dimethylcuprate addition to α,β-unsaturated ketones
Bernasconi,Gariboldi,Jommi,Sisti
, p. 2337 - 2340 (2007/10/02)
The enolates from 1,4 addition of lithium dimethylcuprate to 2-cyclohexenone, 2-cyclopentenone and methyl vinyl ketone, with acetyl chloride, give only C-acylated products and not O-acylated products as previously reported in literature.
